To all whom it may concern Be it known that I, ALEXANDER Lunwio, acitizen of the United States, residing at Bedding, in the county ofShasta and State of California, have invented new and usefulImprovements in Power-Generators, of

which the following is a specification.

This invention relates to a power erator.

It is the object of this invention to prothe power generated by theexpansion of steam or explosion of gases, in a reciprocating engine,into continuous rotary motion through the medium of a hydraulic ejector.

Another object is to provide a substitute for a crank as a means forconverting reciprocating motion into continuous rotary motion, by meansof which loss of energy due to dead centers and momentum w1ll beobviated and a continuous, uniform application of power to a drive shaftmay be obtained.

A further object is to provide a power generator of the above characterwhich is simple in construction and efiicient 1n operation. v

The invention primarily resides in a turbine wheel, a hydraulic ejectorfor discharging a liquid in such manner as to rotate the turbine wheeland adapted to use the same liquid continuously, and means for operatingthe ejector by a reciprocating engine.

The invention further consists of the parts and the construction andcombination of parts as hereinafter more fully described and claimed,having reference to the accompanying drawings, in which Figure 1 is aplan view of the invention. Fig. 2 is an enlarged vertical section onthe line 0-0, of Fig. 1. Fig. 3 is a vertical section in elevation onthe line b?) of Fig. 2, with parts broken away. Fig. 4 is a horizontalsection of the engine cylin- In the drawings A represents a drive shaftwhich is supported in suit-able bearings and has a pair of spacedturbine wheels 2 rigidly mounted thereon. The turbine wheels 2 areincased in separate housings 3 and are provided with the usual turbinebuckets or vanes at on their outer periphthe casings 3, on theirundersides, are nozzles 5, which diverge outwardly from theirconnections with the housings 3 and are connected at their entracted.position tons are in a slightly advanced position.

. position larged outer ends to horizontal cylinders 6, 1n whichgiistons7 are reciprocally mounted.

Forms on the cylinders 6 are annular chambers 8 which communicate withthe intenor of the cylinders through ports 9; the ports 9 being sodisposed as to be open when the pistons 7 are in their rearmost or reandclosed when the pis- The chambers 8 communicate with the interior of thehousings 3 by means of drain pipes or conduits 10, which lead from thehousings 3 at their lowest points, adjacent to the nozzles 5. Thechambers 8 are designed to serve as reservoirs for the liquid employedin operating the turbine wheels 2, which liquid drains from the housings3 into the chambers 8, through the pipes 10 and enters the cylinders 6,through the ports 9, when the pistons 7 are in their rearmost suchquantity of liquid being introduced into the housings 3 as will approximately fill the forward ends of the cylinders 6 and, nozzles 5 when thepistons 7 are in their rearmost positions.

The pistons 7 areconnected to piston rods 11 which extend into englnecylinders 12, and are secured at their outer ends to pistons l3reciprocally mounted in the engine cylinders 12. The engine cylinders 12are arranged parallel with each other and are provided with suitableinlet ports 14, and exhaust ports 15, being here shown as adapted to beoperated by the explosion of gases, which may be delivered to theinterior of the cylinders and exploded in any suitable manare retractedby cushion pressure is preferably employed, but itis manifest that anysuitable means may be employed for reciprocating the pistons 13, asdesired; the essential feature bein to provide means for reciprocatingthe pistons 7 in the cylinders 6.

In the operation of the invention the pistons 13 are reciprocated by theexplosion of gases in the cylinders 12 in a manner common in gas engineoperations, or by the expansion of steam in the well-known manner. Theoperation of the pistons 13 causes the pistons 7 to reciprocate inopposite directions in relation to each other in the cylinders 6, one ofthe pistons moving rearwardly as the other advances. piston 7 moving toits rearmost position uncovers the ports 9 and thereby permits aquantity of liquid i 1 I i i i NDER LUDWIOG, 0F BEDDING, CALIFORNIA.

and arranging the pistons 7 to operate in ejecting alternate streams ofliquid against the turbine wheels, tion of power obtained; one piston 7operatin against a tur a substantially continuous applicato rotate theshaft A w1ll be to eject a ine wheel,

It is manifest that while I have shown and described a air of turbinewheels and ejectors as emp oyed in rotating a single shaft A, the numberof-turbines and ejector-s may.- be increased to any desired extent. Itis also obvious that any suitable means for recipro-- 1 eating theejector pistons 7 may be employed.
